Solar Photovoltaic FAQ’s

Yes. All unused electricity will be exported back to the grid. This is usually paid as part of a guaranteed 50% Export rate. However, systems above 30kWp have to have an Export Meter installed which measures the actual amount.

Systems up to about 10kW peak power can often be accommodated on a single phase electrical supply, however we do need to seek permission from your Distribution Network Operator (DNO). More than this will require 3 phases with the power split equally between them.

For a standard roof we use rigid stainless steel brackets that are fixed directly to your roof rafters. The brackets hook out from underneath your existing tiles. We do not drill tiles/slates or use mastic/silicone to weather proof your roof. These techniques do not have a long life span.

Systems can be as small as 2 panels occupying about 3.3sqm on your roof. A typical 4kWp system (16 panels) will require about 25sqm. However, as an authorised SunPower installer we can provide a 12 panel high efficiency system that is less than 20sqm.
